The present application relates to a method for determining handover criterion in a cellular wireless communication system, said cellular wireless communication system employing handover procedures according to which mobile stations may be handed over from a cell to another cell; said method comprising the steps of: receiving at least one handover control criterion parameter, and determining at least one handover criterion based on said at least one handover control criterion parameter. Furthermore, the present application also relates to a method in a network control entity, a method in a network entity, a computer program, a computer program product, a network control entity device, a network entity device and a cellular communication system comprising such devices.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method, comprising: obtaining, by a network entity in a cellular wireless communication system, parameters associated with a handover control criterion, wherein the handover control criterion is adopted for changing a handover trigger value, the handover trigger value is a cell specific offset that is associated with a threshold at which a cell initializes a handover preparation procedure, and the parameters comprise a threshold value used to define a maximum allowed frequency which indicates how often the handover trigger value is changed and to define a maximum value allowed for the handover trigger value to change; and changing, by the network entity, the handover trigger value according to the parameters.
2. The method according to claim 1 , wherein the obtaining, by a network entity in a cellular wireless communication system, parameters associated with a handover control criterion comprises: receiving, by the network entity, the parameters from a network control entity.
3. The method according to claim 2 , wherein the network control entity is at least one of the following: Operations and Maintenance (OAM) entity, Network Management System (NMS) entity and Element Management System (EMS) entity.
4. The method according to claim 2 , wherein the network entity is integrated in a base station.
5. A network entity in a cellular wireless communication system, comprising a transceiver; and a processor, communicatively connected with the transceiver; wherein the processor is configured to obtain parameters associated with a handover control criterion, wherein the handover control criterion is adopted for changing a handover trigger value, the handover trigger value is a cell specific offset that associated with a threshold at which a cell initializes a handover preparation procedure, and the parameters comprise a threshold value used to define a maximum allowed frequency which indicates how often the handover trigger value is changed and to define a maximum value allowed for the handover trigger value to change; and change the handover trigger value according to the parameters.
6. The network entity according to claim 5 , wherein the transceiver is configured to receive the parameters from a network control entity.
7. The network entity according to claim 5 , wherein the network entity is integrated in a base station.
8. A cellular wireless communication system, comprising a network entity and a network control entity, wherein the network entity is configured to: receive, from the network control entity, parameters associated with a handover control criterion, wherein the handover control criterion is adopted for changing a handover trigger value, the handover trigger value is a cell specific offset that associated with a threshold at which a cell initializes a handover preparation procedure, and the parameters comprise a threshold value used to define a maximum allowed frequency which indicates how often the handover trigger value is changed and to define a maximum value allowed for the handover trigger value to change; and change the handover trigger value according to the parameters; and the network control entity is configured to: send the parameters to the network entity.
9. The system according to claim 8 , wherein the network control entity is at least one of the following: Operations and Maintenance (OAM) entity, Network Management System (NMS) entity and Element Management System (EMS) entity.
10. The system according to claim 8 , wherein the network entity is integrated in a base station.
